REFLEX PHENOMENA IN THE CONTRACTURE STAGE OF PERIPH¬ ERAL FACIAL PARALYSIS. Presented by Dr. A. Myerson. Following the acute phase of peripheral facial paralysis, of whatever origin, there is in the cases that partly recover a phase of contracture. In this period, which comes on gradually after six months or more, the patient superficially presents a picture quite the reverse of the acute phase in that the nasolabial fold on the affected side is more prominent and the aperture of the eye is
more » ... e of the eye is narrower. There is usually some weakness of the face, with so-called associ¬ ated movements, so that when the affected eye is closed the corner of the mouth moves with it. The new phenomena described (illustrated on a patient) are: (1) when an electrode (either G. or F.) is placed on the affected brow and the current turned on, the corner of the mouth twitches before the brow contracts, although the direct excitability of the nerve is lessened; (2) tapping the forehead or the bridge of the nose causes a contracture (reflex) of the affected corner of the mouth.
